Certificate of authenticity: an essential document for artists

A certificate of authenticity, or COA, is probably one of the most essential documents you should include in the process of selling your artwork. Many artists wonder where to start.

What is a certificate of authenticity?

It is an official document that proves that the work is genuine and authentic. It is a useful tool to prove the origin, quality and guarantee to the buyer that the work is produced by the artist himself.

Ideally, it should keep track of all artworks that are built, regardless of whether they sell or not. In the case of a sale, a certificate of authenticity is normally one of the first documents provided to the buyer.

In addition to functioning as a sales receipt, if the work increases in value over time, the COA works as a physical document that “traces” the origin of the work, delimiting who was in its possession.
